HOlSTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 465,114, dated December15, 1891.

Application filed December 31, 1890. Serial No. 376,384. (No model.)

To all whom it may concern.-

Be it known that I, MICHEL JOHN PAUL, a snbj ect of the Queen of GreatBritain and Ireland, residing at 18 Montague Place, Russell Square,London, in the county of Middlesex, England, have invented certain newand useful Means for Ooaling Vessels or Conveying Coal and otherMaterials from Vessels to lVharves or other Places, of which thefollowing is a specification.

In applying this invention, by way of example, to the coaling of a shipI employ lighters, having movable hoppers or bunkers,which can be liftedby mechanical means. The hopper or bunker receives the cargo of coal inbulk. To deliver the coal, the hopper or bunkeris lift-ed so that thecoal is raised above the point atwhichit is required to be dis charged.An inclined trough or chute is then arranged beneath the hopper, and thecoal descending the chute is thereby directed to the desired place. Bysuitable arrangements of the usual kind the descent of the coal can becontrolled or arrested, if necessary. In

order to afford the barge the requisite stability when the loaded hopperis raised, a drop keel or counterbalance is employed. The drop-keel islowered from its normal position while the hopper is being raised, andrises again to its normal position as the hopper descends.

In the accompanying drawings, Figure 1 represents, partly inlongitudinal section and partly in side elevation, a coaling-lighterprdvided with apparatus arranged in accordance with the present invention,the apparatus being in position for enabling the cargo to be discharged.Figs. 2 and 3 are respectively a corresponding transverse section and aplan. Fig. 4. is a transverse section showing the hopper and thedrop-keel or counterbalance in their normal positions.

A is a movable hopper or coal bunker.

1.3 is a drop-keel or counterbalance.

In Figs. 1 and 2 the hopper is raised into position for enabling thecargo to be dis charged, the drop-keel being lowered. In Fig. ithehopper is lowered into the position it occupies when the lighter isgoing from place to place, the drop-keel being raised.

U C are chutes leading from the bottom of the coal-bunker. Each chute ismade in two parts, the outer part O being hinged to the inner part 0.The outer part may be drawn in against the side of the hopper, asrepresented in Fig. 4, when the chute is not in use. D are endlesschains which travel over the bed of the hopper. These chains serve tofacilitate the discharge of the cargo by drawing the coal (which may beshoveled thereon) toward the chutes. Each chain is arranged opposite oneof the chutes and passes round a guiding-drum d and a driving-drum (Z,the latter being keyed on a longitudinal shaft D.

E are shafts mounted in bearings e. These shafts carry drums E for thechains F, by means of which the hopper is raised or lowered. The chainsF pass over guiding-pulleys F. The drop-keel is lowered or raised bymeans of chains T which are coiled on drums E fixed on the shafts E. Thekeel, when lowered, is attached by side chains 1 to each bilge, one setor the other of these chains serving to communicate a righting force tothe barge in the event of the latter being keeled. G is an engine fordriving independently the shafts E and I). The shafts E are driventhrough the bevel-pinions g and g and the worm-shaft The worms on theworm-shaft 9* gear with and drive the wormwheels 9 on the shafts E. Theshaft g is in three parts, which are united by two clutches g". Theseclutches are thrown out of action when it is desired to disconnect theshafts E from the engine. The shaft D is driven from the shaft g throughthe bevcl-pinions g, h, h, 7L2, h and h. The pinion 712 is keyed on thelower end of a-vcrtical shaft H, the pinion 71 being carried in hearingson the hopper and sliding along the shaft ll as the hopper is raised orlowered. The pinion ha is caused to rotate with the shaft l-[ by meansof a feather, which slides in a feather-way cut in the shaft. A clutchor equivalent device is provided between the shafts g and If in orderthat the endless chains 1) need only be driven while the cargo is beingdischargeril.

The means described for disconnecting the shafts E or the shaft 1) fromthe engine G are given by way of example only. Other means foraccomplishing the same end may be devised. Forinstance,the engine G,when working in one direction, may be arranged to drive the shafts E,the shaft D remaining stationary, and when Working in the otherdirection to drive the shaft D the shafts E remaining stationary. Undersuch circumstances the shafts E would be connected to the engine by aclutch capable of communicating motion in one direction only, the shaftD being similarly connected to the engine.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a lighter for coaling vessels or for conveying coal and othermaterials from vessels to Wharves or other places, the combination, withthe vertical guides fixed to the lighter and the movable hopper orcoal-bunker A, guided thereby, of the chutes O C, the endless chains D011 the bed of the hopper, the hoisting and lowering chains F, theshafts E, and the drums E, substantially as and for the purpose setforth.

2. In a lighter for conveying coal or other materials to ships orWharves, the combina-.

tion, With a movable hopper or bunker A, capable of being raised orlowered, of a dropkeel B, capable of being lowered and raised, thelatter serving to partially counterbalance the loaded hopper, and toafford increased stability to the floating structure.

'In a lighter for conveying coal or other materials to ships or wharvesand having a movable bunker A and drop-keel B, the combination, with thesaid bunker and drop-keel, of the chains F and chain-drums E and thechains F and chain-drums E arranged to lower and raise the drop-keel asthe bunker is raised and lowered, substantially as herein described.

4. In alighter for coaling vessels or for conveying coal and othermaterials from vessels to wharves or othervplaces, the combination, withthe movable hopper or coal-bunkerA and vertical guides fixed to thelighter for guiding said hopper, of an endless chain D, travelingon thebed of the hopper, and chutes O C, pivoted to the hopper and serving tofacilitate the discharge of the cargo, substantially as and for thepurpose set forth.
